Depending how accurate you want your 1:5 model to be, there are some detailed 1:72 scale models out there which you might be able to scale up..
Or you can inquire on a AW109 airframe station diagram which is found in the maintenance manual usually under Chapter 6. An example of a Bell 206L3 station diagram is below. This diagram provides exact dimensions from a master datum point to a number of points on the fuselage to include some vertical and lateral points as well. Unfortunately, I do not have access to any 109 manuals.
